According to her manager, the popular fighter had had a “phenomenal camp” in preparation for a fight with Sarah D’Alelio at “Strikeforce: Overeem vs. Werdum” before an “unfortunate setback” prompted her doctor to advise against her participation in the event, which takes place June 18 at American Airlines Center in Dallas.

“She’s bummed out and trained her ass off for this fight,” Scott Karp today told MMAjunkie.com (www.mmajunkie.com) via text.

Strikeforce CEO Scott Coker said today that the doctor had “revoked” Carano’s medical clearance to fight and added that, “The timetable for Gina’s return will be determined after further testing conducted this week.”

Officially, though, Carano was cleared to fight. She had submitted all required paperwork to compete and had been granted a license by the Texas Department of Licensing and Regulation, which is in charge of regulating the event. The paperwork included a physical, blood-test results and an ophthalmologic exam.

“She had met all the state of Texas requirements,” Susan Stanford, a representative for the Texas Department of Licensing and Regulation, today told MMAjunkie.com.

Today, the TDLR received notice from a representative of Strikeforce parent company Zuffa LLC that Carano would not be competing at the event. No reason was given for the withdrawal.

Likewise, Coker declined to comment on the circumstances surrounding Carano’s withdrawal except to read a statement from the fighter.

“I’m seriously disappointed not to be fighting June 18,” Carano’s statement read. “I’d like to thank Greg Jackson and Team Jackson for such an amazing camp. I hope this is only a brief setback.”

Carano had taken residence with Jackson’s MMA academy in Albuquerque, N.M., several months prior to the fight. The trainer praised her abilities and said she had “all the potential in the world.”

When contacted today by MMAjunkie.com, Jackson also declined comment, but he said that “the whole team loves Gina.”

Of course, speculation has run rampant on the reason for the sudden change. However, Karp did say the withdrawal had nothing to do with cold feet.

“Had she been able to compete, she would have handled her business,” he wrote. “That I’m sure of. Hopefully that will happen sooner than later.”

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
